I think I'm going to skip this route for now - see my other emails.

This is good advice anyway for when I build our Asterisk box in the coming months. We'll inevitably stick with ISDN lines for external calls.

We currently have our fax line as a DID number on the ISDN/2 which the Samsung routes to an analogue extension which is then answered using Hylafax on a linux box.

When we move to a full Asterisk solution I'll potentially just have Asterisk route the fax call via DID number to an FXO/FXS analogue line and have Hylafax deal with it as now.
